Units 1 and 2 Semester Review

Front

Discuss the relationship between wavelength, frequency, and energy in the electromagnetic spectrum.

Back

Shorter wavelengths have higher frequencies and energy, explaining why blue light is more energetic than red light.

Front

What does the Kinetic Molecular Theory primarily explain?

Back

Kinetic energy.

Front

What is the primary focus of the 1st Law of Thermodynamics?

Back

Conservation of Energy.

Front

Which of the following best describes thermal equilibrium?

Back

A state where temperature is uniform throughout.

Front

Boyle's PV law: When _______ is held constant, the pressure and volume of a gas are ________ proportional.

Back

temperature, inversely.

Front

Define wavelength in the context of the electromagnetic spectrum.

Back

The distance between successive peaks of a wave.

Front

What is frequency in relation to waves?

Back

The number of waves that pass a point in one second.

Front

Explain the concept of energy in the electromagnetic spectrum.

Back

Energy is directly proportional to frequency and inversely proportional to wavelength.

Front

What is thermal energy?

Back

The total kinetic energy of particles in a substance.

Front

Define entropy in thermodynamics.

Back

A measure of the disorder or randomness in a system.
